Consider two flat-plate collectors with different specifications. The transmissivity, absorptivity, and overall heat transfer coefficient parameters for the single glazing are given as 0.9, 0.9, and 12 W/m²°C, whereas the same parameters for the double glazing are calculated as 0.88, 0.88, and 8 W/m²°C, respectively. The heat removal factor for both collectors is 0.96, the solar insulation is considered 800 W/m², and the ambient temperature is 25 °C. Accordingly, find the following parameters given as: a) The collector efficiency if the water enters the collector at 60 °C b) The temperature of the water at which the collector efficiency is zero c) The maximum collector efficiency considering the incident angle modifier as 1
